ASTRID introduces emergency services paging system in Belgium

Belgium’s emergency services TETRA radio network operator has switched to a new paging system to improve call alerts to fire brigades and first responder volunteers

ASTRID introduces emergency services paging system in Belgium

ASTRID, the operator of Belgium’s TETRA emergency services communications network, has completed the changeover from its old paging system to the new one. Paging is used by the fire brigades and emergency services to call volunteers who are equipped with pagers through which they can receive alert notices.

The important preparations for renovating the infrastructure and ensuring continuity of the service provision in the future started one year ago. ASTRID worked closely together with the user organisations throughout the entire process. During the changeover on Saturday, 4 June 2016, ASTRID constantly kept users informed about the course of events.

The technically complex migration was completed in four hours (between 8am and noon), during which time the paging service was interrupted. Following several months of preparation, the technical teams from ASTRID and its suppliers have done their utmost to ensure a smooth transition.

After the switchover of the 226 antennas in various locations all over the country, the pagers of the volunteer firefighters and emergency responders as well as the alarm terminals at the fire stations automatically connected to the new system.

On the Saturday afternoon the teams carried out on-site technical maintenance on 30 antennas. More than 2.3 million pages pass through the paging network every year. Radio communication was not interrupted during the switchover operation as it did not involve the ASTRID TETRA radio network.

Necessary works
Certain components of the old paging system had become outdated (2001) or had reached end-of-life status and the supplier was no longer able to offer maintenance or a replacement. The paging service is a quintessential tool for calling volunteer firefighters to the fire station.

After consultation with the users it was decided to re-opt for POCSAG, a proven and widely used technology standard that continues to meet the operational needs of the emergency services.

The renewal of the paging system encompasses the replacement of the network core and its auxiliary system (consolidated in three data centres), the gradual replacement of the emitters on the antennas, and the addition of certain features with added value for the users.

After completion of a public procurement awarded in 2015 to the company Thales, the paging technology will be brought up to date from the previous system. This will allow for a reduction in operational costs at the same time.

The users of the paging system
A pager is a device through which volunteers can receive short messages (e.g.: “Urgent intervention – house fire”) or codes transmitted by the station. The main users of this simple and efficient alerting system are the (voluntary) fire brigade, the Civil Protection Service, several medical emergency services, doctors, hospitals and the Red Cross.

The system allows for sending an alarm message simultaneously to a large number of volunteers who possess a pager and are located outside the station (at work or at home). Approximately 6,400 alarm messages pass through the ASTRID paging network every day. Paging subscriptions are free of charge for emergency zones (fire brigade) and public emergency services.

Christophe Grégoire, chief operations officer at ASTRID, said: “This technological upgrade offers a direct operational benefit to the users in the field, i.e. the 12,000 volunteer firefighters who are active throughout Belgium.

“In addition, it ensures continuity of the paging service for another 15 years. I would like to thank all of the users and everyone who has participated in the works for their contribution to this complex migration effort.”

Features and benefits of the new paging system:

  • Messages are transmitted faster as a result of more rapid processing in the centralised system
  • Better redundancy: The centralised systems are redundant and constantly exchange their data between them
  • Advanced system monitoring from the ASTRID Service Centre
  • No need to replace the 21,000 pagers already in use in the field
  • Guaranteed technological support from the supplier of the infrastructure (Thales) for the next 15 years
  • New key features in the longer term: encryption of messages; transmission of acknowledgment of receipt; automatic re-transmission effort in case of failed delivery.
